*Basic Guidelines for Solving Word Problems:*1. Read the problem several times and organize the given information.

2. Identify the variables by assigning a letter to the unknown quantity.

3. Set up an algebraic equation.

4. Solve the equation.

5. Finally, answer the question and make sure it makes sense.

With geometry type problems it sometimes helps if we draw a picture. Here are some area formulas that you are expected to know.

**Geometry Problem**: The length of a rectangular room is 2 feet more than twice its width. If the total area in the room is 220 square feet, find the dimensions of the room.

**Geometry Problem**: A square cement slab is to be surrounded by a 2-foot brick border. If the total area is to be 121 square feet, what are the dimensions of the cement slab?

**Geometry Problem**: A pig pen is to be built adjacent to a barn with 16 feet of fencing. If the length is to be twice that of the width, what will the area of the pen be?

**Geometry Problem**: The height of a triangle is 3 inches less than twice the length of its base. If the total area of the triangle is 52 square inches, find the lengths of the base and height.

**Geometry Problem**: The hypotenuse of a right triangle is 2 centimeters more than the smallest leg. If the longer leg measures 4 centimeters, find the lengths of the other two sides.

**Answer**: The smaller leg measures 3 centimeters and the hypotenuse measures 5 centimeters.

**Geometry Problem**: The hypotenuse of a right triangle measures 10 inches. If the small leg is 2 inches less than the longer leg, find the lengths of the legs.

*t*represents time in seconds,

*v*-naught represents the initial velocity in feet per second, and

*s*represents the initial height in feet.

**Projectile Problem**: A projectile is launched from a roof 80 feet high at an initial velocity of 64 feet per second. How long will it take the projectile to land on the ground?

**Projectile Problem**: Old fashioned large caliber handguns (45 Colt, 44 S+W) shoot a heavy bullet without a lot of gun powder behind it. Muzzle velocities for these weapons average 1,000 feet per second. If a handgun is shot up into the air from the ground how long will it take to bullet to come back to the ground? (Wind and air resistance are not part of this calculation)

**Projectile Problem**: Using the previous problem, how high is the bullet at

*t*= 30 seconds?

**Projectile Problem**: If a rocket is shot straight up with an initial velocity of 48 feet per second, then its height

*h*, in feet, after

*t*seconds is given by\

b. When is the rocket exactly 32 feet above the ground?

c. When will the rocket hit the ground?

**Word Problem**: Find a polynomial that gives the area of a circle of radius

*x*with a square, whose diagonal measures 2

*x*, cut from it.
